NAME

       perlivp - Perl Installation Verification Procedure

SYNOPSIS

       perlivp [-p] [-v] [-h]

DESCRIPTION

       The perlivp program is set up at Perl source code build time to test the Perl version it was built under.  It can be used after running:

	   make install

       (or your platform's equivalent procedure) to verify that perl and its libraries have been installed correctly.  A correct installation is
       verified by output that looks like:

	   ok 1
	   ok 2

       etc.

OPTIONS

       -h help
	    Prints out a brief help message.

       -p print preface
	    Gives a description of each test prior to performing it.

       -v verbose
	    Gives more detailed information about each test, after it has been performed.  Note that any failed tests ought to print out some
	    extra information whether or not -v is thrown.

DIAGNOSTICS

       o   print "# Perl binary '$perlpath' does not appear executable.
";

	   Likely to occur for a perl binary that was not properly installed.  Correct by conducting a proper installation.

       o   print "# Perl version '$]' installed, expected $ivp_VERSION.
";

	   Likely to occur for a perl that was not properly installed.	Correct by conducting a proper installation.

       o   print "# Perl @INC directory '$_' does not appear to exist.
";

	   Likely to occur for a perl library tree that was not properly installed.  Correct by conducting a proper installation.

       o   print "# Needed module '$_' does not appear to be properly installed.
";

	   One of the two modules that is used by perlivp was not present in the installation.	This is a serious error since it adversely affects
	   perlivp's ability to function.  You may be able to correct this by performing a proper perl installation.

       o   print "# Required module '$_' does not appear to be properly installed.
";

	   An attempt to "eval "require $module"" failed, even though the list of extensions indicated that it should succeed.	Correct by
	   conducting a proper installation.

       o   print "# Unnecessary module 'bLuRfle' appears to be installed.
";

	   This test not coming out ok could indicate that you have in fact installed a bLuRfle.pm module or that the "eval " require
	   "$module_name.pm"; "" test may give misleading results with your installation of perl.  If yours is the latter case then please let
	   the author know.

       o   print "# file",+($#missing == 0) ? '' : 's'," missing from installation:
";

	   One or more files turned up missing according to a run of "ExtUtils::Installed -> validate()" over your installation.  Correct by
	   conducting a proper installation.

       For further information on how to conduct a proper installation consult the INSTALL file that comes with the perl source and the README
       file for your platform.
